From 1d0704f4d79335f8a4fee8d69bdd3c291e25de91 Mon Sep 17 00:00:00 2001 From: Ajit Khaparde Date: Wed, 15 Jun 2016 14:23:05 -0700 Subject: [PATCH] net/bnxt: add device configure operation The dev_configure_op function calls bnxt_set_hwrm_link_config() to setup the PHY. This calls the new bnxt_parse_eth_link_*() functions to translate from the DPDK macro values to those used by HWRM calls, then calls bnxt_hwrm_port_phy_cfg() to issue the HWRM call. New HWRM calls: bnxt_hwrm_port_phy_cfg: This command configures the PHY device for the port.
